Abstract
(EN)
Disclosed is a data transmission method, belonging to the technical field of wireless communication. The method is executed by a base station. The method comprises: sending bandwidth part (BWP) configuration information to a terminal, wherein the BWP configuration information includes time domain indication information, and the time domain indication information is used to indicate time domain resources where the BWP configuration information takes effect; and performing data transmission with the terminal on the time-domain resources indicated by the time domain indication information. According to the solution, the time domain of a BWP of a terminal is flexibly configured by means of BWP configuration information, so that the problem that the flexibility of BWP configuration is insufficient caused by the fact that the time domain information of each BWP of the terminal is fixed and the time domain is continuously configured is avoided, thereby improving the utilization ratio of system resources.

L'invention concerne un procédé de transmission de données relevant du domaine technique de la communication sans fil. Le procédé est exécuté par une station de base. Le procédé comprend les étapes consistant à : envoyer à un terminal des informations de configuration d'une partie de bande passante (BWP), les informations de configuration de la BWP contenant des informations d'indication de domaine temporel et les informations d'indication de domaine temporel étant utilisées pour indiquer des ressources de domaine temporel dans lesquelles les informations de configuration de la BWP sont actives ; et effectuer une transmission de données avec le terminal sur les ressources de domaine temporel indiquées par les informations d'indication de domaine temporel. D'après la solution, le domaine temporel d'une BWP d'un terminal est configuré de manière flexible au moyen d'informations de configuration de la BWP, ce qui prévient le problème de la flexibilité insuffisante de la configuration de la BWP due au fait que les informations de domaine temporel de chaque BWP du terminal sont fixes et que le domaine temporel est configuré en continu. Le taux d'utilisation des ressources du système s'en trouve amélioré.

本公开揭示了一种数据传输方法,属于无线通信技术领域。所述方法由基站执行,所述方法包括:向终端发送带宽部分BWP配置信息,所述BWP配置信息中包含时域指示信息,所述时域指示信息用于指示所述BWP配置信息生效的时域资源;在所述时域指示信息指示的时域资源上,与所述终端之间进行数据传输。本方案实现了通过BWP配置信息对终端的BWP的时域进行灵活的配置,避免因为将终端的各个BWP的时域信息固定且时域连续配置而导致BWP配置的灵活性不够的问题,从而提高系统资源的利用率。
